PSG can be the main advertiser but PSG can't offer the huge marketing share and potential that Barcelona is already offering Qatar. The benefit Qatar is getting from being a business partner with Barcelona is huge comparing to PSG. So if you want to talk business, the owner will be very very careful not to upset a club like Barcelona which is already a business partner with Qatar. Capisce?
Hahaha ! Again this contemptous tone...
And you don't knwo wat you are talking about. At the moent, it's clear that PSG as little visibility compared to Barça. But Qatar benefits far from PSG than Barça. Our ex french president (namely Sarkozy, who is PSG fan) pushed for the Qatari investments in PSG. Qatari, aswell, got great tax laws from their investments in France and Paris as a result.
QSI it's also Bein Sport, a chain who earn the French Ligue 1 rights. So the stronger is PSG, the stronger it benefits from them.
Then, the argument like what the PSG owner doesn't want to make Barça angry, so he'll sell TS is the biggest bullshit i've ever heard. In that case, why did PSG outbid Barça last year when this latter was interested in ? As you said, Qatar isn't philanthropic, this is all business. They sponsored the best team of the decade, which give them great visibilty (and you are well paid for that). In the other hand, they earn a club and they want him to reach success.
Do you ever see businessmen who are willing to put their own business in jeopardy just to help their partners ?
Anyways, i don't see why keeping your own player would upset anybody. You are talking like if Barça has some rights over TS...
And to end, we are in an english forum, so no, i don't capisco.
Edit: i don't give credit to those self-named specialists but geopolitcal specialists are even saying that now PSG owner is the new Cheickh he will push even harder in the way of the soft-power and is willing to give PSG more visibility by hiring big players. But i rate this judgment at least as high at yours.
